These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Batman: No Man's Land
Anticlimax Boss: Depending on how you view the ending, or if you were waiting for Joker's big move to either happen earlier or be larger in scope and body-count, the ending, chilling though it be, can come off thusly.
If you were looking for a grand rematch between Batman and Bane, sorry. Their meeting was fairly civil — but, somewhat paradoxically, still manages to be awesome.
Crowning Moment of Heartwarming: The scene where Gordon chews out Batman for abandoning Gotham, and Batman takes off his cowl in order to regain Gordon's trust. Gordon doesn't look and instead tells him to put it back on.
Magnificent Bastard: Lex Luthor. He sets up the whole No Man's Land policy himself from behind the scenes, sends Bane in to alter the records to show that he owns a bunch of property in Gotham, then shows up, fixes everything (which, remember, only needed fixing because of him in the first place), and uses the positive publicity to boost a successful campaign for President of the United States. Sure, the real estate scam angle didn't pan out because Batman figured out what he was doing, but otherwise the whole thing was a roaring success.
Tear Jerker: The death of Jim Gordon's wife, Sarah, at the hands of the Joker. Joker has a large number of infants held hostage. Sarah rushes in with a gun, and Joker tosses one of the babies at her, forcing her to drop her gun to save it. No points for guessing what he does once she's unarmed. Gordon gets the news outside - he rants tearfully about how the Joker has gone too far and seriously considers killing him, but after shooting him in the knee, chooses law over anarchy and walks away. And if him weeping on the steps as Batman holds him steady doesn't get to you, then the scene of him spending the New Year alone, singing Auld Lang Syne dry-eyed over Sarah's grave definitely will.
To put this event into perspective: Even The Joker realizes that this wasn't funny, even by his standards.
OTOH, Joker found Gordon blowing off one of his kneecaps to be hysterical.
Joker: He shot my knee! I may never... ...oh... Like your daughter! I GET IT! Good one, Commissioner!
In the novelisation, Batman's last scene: visiting his parents' grave and the remains of quake-ravaged Wayne Manor: "I'm home."
